The friction pair of piston ring-cylinder liner for the piston ring seal device of Stirling Engine is plastic-metal friction pair, its working conditions for dry friction. So the wear resistance of the piston ring is poor, its service life is short. This paper regard integral non-backpressure piston rings group as the research object in order to reduce wear: First, establishes auto-free lubricating mechanical model to piston rings group; Then, set up the mathematical model, which to meet the
more » ... hich to meet the requirements of the sealing performance, for friction analysis; At last, Experimental analysis in the Piston Ring Seal Device of Stirling Engine to prove that this model is correct and available.
